This is a known issue. We have an internal case CMPLRIL0-25481 to track it.

Thanks for the reply. Is there a workaround for now or do we have to wait for the next point release?

[Viet_H_Intel]

I dont see a workaround suggested in the case. So, I guess you have to wait for the fix.

Thanks,

[doppler_shift]

Any ETA for this fix? this bug is currently blocking our upgrade from ICC 18 to 19, which in turn is blocking us from using all the C++17 features that all other compilers support.

[doppler_shift]

Still not fixed with Intel C++ 19.0 Update 2.

[doppler_shift]

Still not fixed with Intel C++ 19.0 Update 3.

[Fein__Aaron_Max]

this also seems like a blocker, eagerly awaiting fix :)

[doppler_shift]

Still not fixed with Intel C++ 19.0 Update 4.

It's been nearly half a year since I originally reported this bug and we're still blocked from switching to v19. Is this ever going to get fixed or should we just give up waiting for it?

[Viet_H_Intel]

It should be fixed in 19.0 Update 5.
